But is it only in that which moves itself in place that there must be a point at rest, or does this hold also of that which causes its own qualitative1 changes, and its own growth? Now the question of original generation and decay is different; for if there is, as we hold, a primary movement, this would be the cause of generation and decay, and probably of all the secondary movements too. And as in the universe, so in the animal world this is the primary movement, when the creature attains2 maturity3; and therefore it is the cause of growth, when the creature becomes the cause of its own growth, and the cause too of alteration4. But if this is not the primary movement then the point at rest is not necessary. However, the earliest growth and alteration in the living creature arise through another and by other channels, nor can anything possibly be the cause of its own generation and decay, for the mover must exist before the moved, the begetter5 before the begotten6, and nothing is prior to itself.
